[R] Best Way to Compute/Approximate(?) Probabilty of a Point in a Given Distribution

[Gundala Viswanath]

AFAIK, R only has "pnorm" which computes the probability of getting a
value smaller or equal to "x" from
a normal distribution N[mean,stdev]. For example:

R> pnorm(0, 4, 10)
[1] 0.3446

means there is  34.46% chance of getting a value equal to or smaller
than 0 from a N(4, 10) distribution.


What I intend to get is: given the observed value "x", mean, and stdev
of normal distribution,
find the probabiltiy of "x" falls into that distribution.

Is there any reasonable way to obtain that?
